3 Claims.

This invention is a guide for the shuttles in the upper cells of avertically reciprocating drop box loom to locate each one in the rightposition where it will be in the right position to receive a bobbin froma battery or amagazine, and where it will not strike the picker as thedrop box moves up or down in case the picker rebounds, or gets out ofplace for any other cause.

To locate the shuttle in the correct position and to line up theshuttles in the upper cells, it is convenient to move any projectingshuttle by pushing on or guiding its metal point. However, if theshuttle is moving with the box against any kind of a guide, even if theguide is metal, the shuttle point cuts a groove in the guide. Such agroove constantly gets deeper with the result that the position of theshuttles will gradually shift horizontally thus causing any bobbin whichis being transferred to engage the shuttle in the wrong position andthus produce a jam.

To correct this fault, I provide a movable guide which can be adjustedhorizontally to compensate for any wear on the guide by the point of theshuttle.

In the drawing, Fig. 1 is an elevation of a loom, with parts brokenaway, and with my device in place. Fig. 2 is an elevation of the shuttlebox guide with the shuttle guide removed. Fig. 3' is a plan view of mydevice in place.

Fig. 4 is an elevation of a modification and Fig. 5 is a view similar toFig. 1 of the same modification.

Fig. 6 is an elevation and Fig. 7 is a plan View, partly in section, ofother modifications.

In the drawing, A represents a loom frame which, as shown in Figs. 1, 2,and 3, carries a revoluble magazine or battery C of a well known type. Fis a transfer hammer which cooperates with other parts to transfer abobbin B from the magazine C to the top one of the shuttles S such as IIor l2, shown as carried in a drop box D having two cells I and 2.

The lay L, which moves back and forth as is customary, carries the dropbox D and a picker P, shown as movable on a rod such as 3 and as havinga stop 4 of a well known construction.

E represents a drop box guide member with a side face 5 which serves asa guide for drop box D. Member E is of the usual construction exceptthat its front face 6 is flat and through it pass the Shuttle guidemember G is formed with the two supporting arms 31 and 38. The slots 35and 36 pass through arms 31 and 38 and the shuttle point guide face ofmember G is straight at the upper part 39 and'curves downand out nearthe bottom 40 so that as the drop box D moves up, guided by box guideface 5 of member E, the metal tip of any shuttle which protrudes fromone of its cells will strike the part 40 of shuttle guide member G andas it continues to move up, the shuttle such as H or I2 is moved backinto the correct position. The top of this shuttle guide member G asshown in Figs. 1 and 2, extends up to a point as high as the top of thedrop box D ever reaches.

In some types of revoluble magazine looms and especially in hand fedlooms, a relatively high drop box guide such as E is preferable. Loomsof this kind are in general use where there are drop box shiftingdevices to so move the drop boxes as to change a working shuttle of onecolor'to one of another color. In other types of looms such, forinstance, as those which have a fixed magazine M shown in Figs. 4 and 5,a drop box guide such as H which is of less height than E is preferableWith a tall drop box guide such as E, I preferably use a tall shuttleguide member G but with this last type of loom with a low drop box guidesuch as H, I use a relatively low shuttle guide K attached to it by onebolt passing through one slot 5| in guide K and a hole 52 in guide H.

In the construction shown in Figs. 1, 2 and 3 where there is arelatively high arm or blade with I two slots, the shuttle guide can bemoved horizontally and also to a limited extent its guiding surface canbe changed from the vertical.

As shown in Figs. 4 and 5, shuttle guide K has a vertical blade 54 witha shuttle guiding surface 55 which is curved outward at the bottom 56 soas to catch the nose of a shuttle as it moves upward with a drop box.Guide K is carried by a narrow blade or arm 53 which extends at rightangles to blade 54. Slot 51 passes through this arm 53. On box guide His a horizontal guideway 51 in which the arm 53 is slidable. By themeans of a bolt 50 and a nut 58, shuttle guide K can be movedhorizontally but its guiding face 55 cannot be changed from the verticalor from its original angle whatever that may be.

As shown in Fig. 6 I may use a drop box guide J with a smooth face 42through which is a hole 63. In this case, the shuttle guide N can have aguiding face 44 which extends down and out at 46 and, as shown, iscarried by an integral arm 45 through which is a hole 41 for a bolt 48carrying a nut 49. In this case, there is no horizontal adjustment butthe whole guide N can be shifted with bolt 48 as a pivot.

Another variation is shown in Fig. 7 where the drop box guide is shownas having an arm 60 through which is a horizontal hole 6|. Shuttle guideR is carried by an arm 62 which passes slidably through the hole 6| anditself has a threaded hole 63.

61 is another integral arm extending from drop box guide 0. Through arm61 is a hole 69 which registers with hole 63. An adjusting member 66passes through hole 69 and has a screw shank 64 which engages thethreads in hole 63. Member 66 held in place by a collar 65 and a turninghead 68, so that by turning head 68 guide R can be moved back and forthas shown by the dotted lines to regulate the position of a shuttle suchas S.

I claim:

1. The combination in a drop box loom including a frame and batterycarried thereby together with a lay which carries a verticallyreciprocating drop box with a plurality of shuttle cells, a picker and adrop box guide pierced with an adjusting bolt hole and positionedopposite the outer end of the drop box; of a vertical shuttle guide ofL- shape in horizontal cross section, the guide having a horizontaladjusting slot; with an adjust-r ing bolt which passes through the slotin the shuttle guide and through the hole in the drop box guide.

2. The combination in a drop box loom including a frame and batterycarriedthereby together with a lay which carries a verticallyreciprocating drop box with a plurality of shuttle cells, a picker and adrop box guide positioned opposite the outer end of the drop box; of avertical shuttle guide; with means to adjust it horizontally on the dropbox guide.

3. The combination in a drop box loom including a frame together with alay which carries a vertically reciprocating drop box with a pluralityof shuttle cells, a picker and a drop box guide positioned opposite theouter end of the drop box; of a vertical shuttle guide; with means toadjust it on the drop box guide.
